Seeing an Image
... Put the laser on the left side of the prism Shine the laser at the prism and make sure that it comes out the right side of the prism. Use the edge of an index card to locate the beam as it enters and exits the prism. Trace the path of the light beam as you did in Part 2. (see the figure above) ...

Youngs Double Slit
... The double slit slide has several sets of slits. Use black tape to leave one set of slits only. Set up the white light or white LED source on the optical bench. Bring the slit up close to the eye and view the light source. What do you see? The interference pattern can only occur when the light diffr ...

The Wave-Front Aberration Polynomial
... Ray Aberrations Rays represent the direction of wave-front propagation. Therefore, rays point in the direction of the wave-front surface normal and can be calculated as the wave-front gradient. The “transverse ray aberration” (TRA) is the distance, orthogonal to the optical axis, between a paraxial ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
